Add a setting to show time to first window draw and frames per second in status bar (#16422)

I want to showcase Zed's performance via videos, and this seemed like a
good way to demonstrate it.

Release Notes:

- On macOS, you can now set assign `performance.show_in_status_bar:
true` in your settings to show the time to the first window draw on
startup and then current FPS of the containing window's renderer.
